The International Organization for Migration (IOM) is the leading international organization working in the field of migration and works closely with governmental, intergovernmental and non-governmental partners to provide a humane response to migration challenges. Established in 1951 as an intergovernmental organization to resettle European displaced persons, refugees and migrants, IOM has grown to encompass a variety of migration management activities throughout the world. With 166 member states, a further 8 states holding observer status and offices in over 100 countries, IOM is dedicated to promoting humane and orderly migration for the benefit of all. IOM joined the United Nations system as a related organization in September 2016 during the United Nations General Assembly high-level summit to address large movements of refugees and migrants. The IOM Mission in Ukraine was established in 1996 in Kyiv and at the same time Ukraine became an observer state of IOM. In 2001, Ukraine requested membership in IOM and in 2002 the Ukrainian Parliament ratified this membership. With missions worldwide, IOM helps governments and civil society through: rapid humanitarian responses to sudden migration flows, post-emergency return and reintegration programmes, assistance to migrants on their way to new homes and lives, facilitation of labour migration, assisted voluntary return for irregular migrants, recruitment of highly qualified nationals for return to their countries of origin, aid to migrants in distress, training and capacity-building of officials, measures to counter trafficking in persons, migration medical and public health programmes, mass information and education on migration, and research related to migration management and other services for migrants. The IOM Mission in Ukraine operates five programmes: Capacity Building in Migration Management, Counter-Trafficking in Human Beings, Humanitarian and Social Programmes, Migration Health and Migration Management, Emergency and Stabilization. Each programme partners with non-governmental organizations (NGOs) and various government bodies to provide Ukraine with increasingly comprehensive responses to migration challenges.
